T0 @ZZ whom t may concern:

Beit known that we, JOHN ELwIN Evnnnn, a subject of the Queen of GreatBritain and Ireland, and DEMosrHENEs GEORGE PAPPA, a subject of the Kingof Greece, residing in London, England, have invented certain new anduseful Improvements in Velocipedes or Motor-Cycles, of which thefollowing is a speciication.

This invention relates to improved means whereby the handle-bar and thepedals of velocipedes and inotor-cycles can be brought into suchpositions that the machine shall take up less room than usual when notin use. A further object is to provide improved means for transmittingthe driving power from the cranks to the drivin g chain-wheel and forenabling the cranks to be thrown out of action when required. Y

For the purposes of our invention we fit the handle-bar to thesteering-head in such a way that it can be turned to lie parallel with'the wheels, and can also be rotated round its own axis to enable thehandles to be turned down. It may also be so arranged that it can bemoved or slid backward when so turned with an endwise or longitudinalmovement. These various movements insure that the handles shall neitherproject laterally from the inachine nor yet above it to any appreciableeX- tent. We also arrange that the pedals can be turned back to lieinside the cranks and can be locked in this position, as well as intheir working position. We also arrange the chain-wheel loosely on itsaxle and provide a movable connection between it and the crank -adjacentto it, whereby the driving power is transmitted to the said wheel nearthe rim thereof instead of through the axle, and whereby also the crankscan be thrown out of gear when desired.

Our invention will be readily understood on reference to theaccompanying drawings, in which` Figure l is a side elevation, and Fig.2 a plan, of a bicycle, with certain parts omitted for sake ofclearness, having our improvements applied thereto. Fig. 3 is a detachedview showing the handle-bar in plan in the several positions mentioned.Fig. l is a front vtween the crank and chain-wheel.

view, Fig. 2 a side view, partly in section, and Fig. 3f a correspondingview, showing the means we adopt to prevent any unintentionaldisengagement of the clutch when riding over rough roads or otherwise. VIn Fig. 2 the parts are shown engaged, whilein Fig. 3a they are showndisengaged. Fig. 4t is a vertical setA tion, and' Fig. 5 a side view, toa larger scale, partly in section, of the steering-head and handle-bar.Fig. G is a side View, and Fig. 7 a longitudinal section, showing, alsoto a larger scale, the arrangement forturning back the pedals and fortransmitting the driving power to the chain-wheel. Fig. S is a sectionon the line :r it ot' Fig. 7, showing a slight modification of themovable connection be- Fig. 9 shows, diagrammatically, the pedals turnedinward out of the way.

In carrying out our invention we connect the Tepiece a of the handle-bara with the steering-post Z9 by means of a spring-clutch, whose movablepart c is secured to the stem of the T-piece, while its fixed part c'issecured to the said steering-post. These parts c c haveslightly-tapering teeth or projections which engage with each other.They are provided with lugs c2, through which pass tightening-bolts c3,and contraction under the action of the bolts is allowed for by slots c4near the lugs. The clutch can be disconnected by pulling the handle-bar,and with it the T- piece, slightly upward, thereby setting these freeand allowing the handle-bar to be turned in the direction of the arrows,Fig. 2, into the desired position parallelto the wheels, as indicated ata2, Figs. l and 3. The parts of the clutch are normally kept together bya spiral spring c5, extending from a projection c6 in the T-piece to across-piece b in the steering post, and a pin or rod d, secured to thiscross-piece, passes up through the spring and through a steadying-blockd in the T-piece, this block being, however, free to turn relatively tothe stem. The upper extremity of the rod projects through one or otherof two pairs of holes e e', formed in the handle-bar, and suitablemeans, such as a spring-catch or a Cotter-pin, maybe provided at theupper end of the rod for locking it and the T-piece to- IOO gether, soas to prevent the handle-bar boing accidentally raised and disengaged bythe pull of the rider, as when ascending inclines. When the handle-baris raised, as before mentioned, to disengage the clutch, the said holesclear the pin or rod d, and the handle-bar can be rotated round its ownaxis to turn the handles down fromthc position a2, Figs. l and 3, inwhich they project laterally into the positions a2, in which they arevertical or practically so. The position of the holes is such that thepin or rod enters one pair of them, namely, c, when the handles are intheir ordinary position, and the other pair e' when the handles areturned down.

The endwise or longitudinal movement of the handle-bar by which it maybe brought into the position ai, Figs. l and 3, is provided for by themethod of iitting the same in the tubular cross portion or collar of theT-piece. This collar is of larger diameter than the handle-bar to enableit to pass the bends of the said bar, and abush or sleeve f is securedon the center part of the handle-bar to fit the T-piece firmly. Aspring-pin or other suitable movable stop f is fitted in the T-piece andengages a groove f 2 in the bush or sleeve to normally lock thehandle-bar against endwise or longitudinal movement. lVhen, however, thepin or stop f is disengaged, the handle-bar can be pushed back endwisethrough the tubular portion or collar, say, up to the bend in the saidbar, and at this point a second bush or sleeve fx, corresponding to thatabove mentioned, Fig. 2, is advantageously provided on the handle-bar toenter the T- piece and form a secure fitting therein.

Z is a ring having on its interior a screwthread Z and on its exteriortwo milled portions Z2 to facilitate screwing up or down. This ring isheld in place by screws Z3, which project into an annular groove Z4 inthe fixed part c' of the clutch, so that said ring is free to turn, butcannot move up or down. The movable part chas a screw-thread cx, adaptedto engage the internal screw-thread Z. Thus it will be seen on referenceto Fig. 2 that it is impossible to disengage the parts of the clutch bya simple pull, it being necessary both to pull the handle-bar upward,and with it the movable part c', and at the same time to unscrew thering l. In a similar way in order to engage the clutch it is necessaryto screw the ringl so that it draws the screw part c into it. It will ofcourse be understood that no actual downward pressure is necessary inthis case, as the spring c5 constantly tends to bring the parts of theclutch into engagement. With this arrangement it is unnecessary for thepin or rod d to project through the T-piece of the handle-bar.

If an ordinary brake be used, its lever and connections are arranged sothat they do not interfere with the movements of the handlebar, but wefind it advantageous to use apneumatic brake, as the flexibleconnecting-tube of the same obviously requires no special adaptation inapplying it to our improved cycle.

The pedals g are hinged or pivoted in order to enable them to be turnedinward, for which purpose their pins or spindles g have enlarged bossesg2, mounted in the forked extremities of the cranks 71. Locking-leversz', acted upon by springs t", tending to keep them in the workingposition, are arranged in grooves or recesses 7L in the inner sides ofthe cranks and serve to keep the pedals firmly in both their operativeand inoperative positions. The end of each locking-lever carries a wedgeor other suitably-shaped head 2, which abuts against an inclined face g2on the boss g2 of the pivoted pedal-pin, and so locks it in its workingposition. The wedge-shaped head has also a flat-tened point or nose3,which bears against a corresponding fiat portion g4 on the pedal-pinboss g2 when the pedal is turned back into its inoperative position, asindicated in dotted lines in Fig. 7 and in full lines in Fig. 9, soholding the said pedal steady in such position. In the back of the head712 of the locking-lever a hole i4 is formed for the insertion of aninstrument to force back the locking-lever when it is desired to turnthe pedal from one position to the other.

A removable spring (or catch) 5 may also be provided to rigidly connectthe wedgeshaped head and the crank, and so better retain the head in theworking position, and the pin may be tapered to enable it tomake up forwear of the parts.

The fulcra i of the locking-levers are carried by lugs h2 on the cranks,as shown. The short arm of that lever next the driving chainwheel 7c hasa nose or projection 7, adapted to enter an aperture 7a in one of thespokes of the said wheel, or in a plate secured to two of the spokes,and forms the movable connection before mentioned between the crank andchain-wheel, `the parts being so arranged that when the locking-lever isholding the pedal in its working position, as indicated in full lines inFig. 7, the nose or projection 7 is engaging the said wheel, while whenin its inoperative position the said nose or projection is clear of thewheel. The latter is mounted loose on the crank-axle instead of beingkeyed thereto, as is usual, and there is therefore no rigid connect-ionbetween the said wheel and the crank when the pedals are not in use.This is of advantage, for example, when the machine is being pushedforward or propelled by mechanical power, as the wheels can turn and yetthe cranks can remain at rest. Moreover, by transmitting the power tothe chain-wheel, near the rim thereof, a much more efficient drivingaction is obtained, and vibration is greatly diminished.

Obviously instead of the short arm of the locking-lever having a nose orprojection it may be forked, as indicated at 8, Fig. 8, so as to clip orembrace one of the spokes (indicated in dotted lines) of thechain-wheel. This construction is more especially applica- IOO TIO

ble to chain-Wheels whose spokes are too thin to admit of a hole, suchas 7c', Fig. 7, being formed therein.
